WebSep 5, 2024 · A subset of R is said to be open if for each a ∈ A, there exists δ > 0 such that B(a; δ) ⊂ A. Example 2.6.1 Any open interval A = (c, d) is open. Indeed, for each a ∈ A, one has c < a < d. The sets A = ( − ∞, c) and B = (c, ∞) are open, but the C = [c, ∞) is not open. Solution Let δ = min {a − c, d − a}. Then B(a; δ) = (a − δ, a + δ) ⊂ A. WebFor two sets A and B, the proper subset relation A ⊂ B implies that B contains at least one element which is not contained within A. Denoting the null set with ∅, the statement A ⊂ ∅ would imply that ∅ contains at least one element which is not in A. However, the null set contains no elements, so the statement is impossible.

(2) The intersection of closed sets is closed, since either every set is R and the intersection is R, or at least one set is countable and the intersection in countable, since any subset of a countable set is countable. (3) A nite union of closed sets is closed, since a nite (or countable) union of countable sets is countable. It

WebIf there are two sets X and Y, $ X = Y $ denotes two sets X and Y having same cardinality. It occurs when the number of elements in X is exactly equal to the number of elements in Y. In this case, there exists a bijective function ‘f’ from X to Y. $ X \le Y $ denotes that set X’s cardinality is less than or equal to set Y’s cardinality.
